Application filed September 14, 1920. Serial No. 410,158.

the following is a speciiication.

. rlhis invention relates to vehicle. supports, and more particularly to an auxiliary spring structure, and has for its object to provide connection between main for resilient springs and a vehicle trame structure.

A further object ot the invention is to provide an auxiliary leali' spring struc-ture between each end of a spring and a vehicle traine.

lt is an important object ot the present invention to provide a type ot auxiliary spring interposed between main springs and a vehicle frame, of sucli construction as to provide for long life of the parts and secure the desired cushioning of the relatively movable elements.

rThe invention possesses other objects and vfeatures ot advantage, some oi' which, with the foregoing, will be made manifest in the following description of' the preferred torni ot the invention which is illustrated in the drawings accompanying and orining part or", the specification; It is to be'understood that it is not intended toV limit the invention to'the embodiment shown! bythe said drawings and description, as variations may loe-adopted within the scope of the invenn the drawing, Figur-e l is aside elevation of ain end portion of a vehicle trame and an associated axle.

lt has been proposed to secure an auxiliary and'cushioning'spring connection be- :tween theends ot part-elliptic springs attached to an axle, and a vehicle traine, but

tion consists in lea-tor laminated spring devices substantially ot cantilever form, each device connected at one end to a vehicle iframe and at its opposite end to the con` tiguous end of a semi-elliptic spring, with intermediate fulcra connecting the auxiliary springs to the traine.

A torni of the invention is shown here-l with in which an axle 2 is provided with a semi-elliptical leaf spring 3, extending substantially parallel to and below a side coinponent 4C of a vehicle frame. One end of the top leaf of thel main spring 3 is pivotally f connected at 5 to a shackle 6, which, in turn, is pivotally connected to a holding device shown as `a box vor" housing in which is l secured the contiguous ends of a series of spring leaves forming an auxiliary spring 8, the remote end ot the auxiliary spring being pivotally connected by suitable means at 9 to the trame 4. The auxiliary or intermediate spring 8 is pivoted at a point 10, between its connections 6 and 9, with the mainspring and trame, respectively, so

'that upon downward movement of' the traine, with respect to the springs 8, there is an upward thrust or the shackles 6 on the short end ot the cantilever-like spring 8, lwhich movement is against the reaction ot the leaves oic the spring between the tulcruin 10 and the connection 9; the auxiliary spring istherefore fulcrumed intermediate its ends tothe vehicle frame, and the auxiliary spring comprises a lever, one arm of which is tlexible, consisting ot a vmultiple lea-t spring and the other arm of which is rigid, comprising the box or clamp 7. The auxiliary spring thus comp-rises a lever havinga flexible long arm and a stii or rigid short arm.r

The opposite end of the main spring is pivoted at ll to a device in the torni of a holder or box 12, in which is suitably secured the ends of a set ot laminated spring leaves forming another auxiliary spring 13, whose end remote fromthe box 12 is pivoted to a shackle or other suitable connection 14, attached to the contiguous .portion Vot" the trame 11@ "Intermediate the pivots 11 and la ot the auxiliary spring lris a ulcrum 15 that may' consist of a `pin or rod adjustable in one oranother of a series of transverse pin holes 16, provided in a portion of, oi' on, thebox 12, sothat the desired reaction ot the cantilever spring 13 may be secured. Connected to the fulcruin 15 is a linl; device 17 in the form of a pair of side arms, the lower ends of which are pivotally connected at 18 to the horn, or other downwardly bowed portion at 19 adjacent the end of the frame et.

The reaction of the cantilever spring 13 is similar to the spring 8, in that when the frame 1 moves downwardly, with respect to the spring 8, there is a tendent-y of the box 12 to move upwardly in a direction reverse to the spring 13 as the latter rocks about its fulcrum 15.

From the above it will be seen that the invention provides a type of auxiliary cushioning springs of a form having great strength and longevity, and which also is of a well known, practicable character of spring, the whole being inexpensively manufactured and applied substant-ially without reconstruction or alteration of the usual main spring parts and frame construction.

In Fig. et, the invention is embodied with a frame #1, having niain leaf springs 3 at each end, one end only of each of which springs is attached to the main frame, or parts thereon, and one end of each main spring is connected to one end of an interposed cantilever or leaf spring 13. The leaf spring 13 at the front end Ll of the vehicle frame, is attached by a saddle '120, having a fulcrumed pin 21 on which the leaf or cantilever spring 13 `is mounted intermediate its ends. r1`he frontend of the leaf spring 13 is attached by al shaclrle 22 to the front end frame` a, while the rear end of the leaf spring 13 is connected at 23 to the rear end of the main frame. rlhe auxiliary spring at the rear end of the frame is mounted substantially as shown in Fig. 1. ln some cases the vehicle frame may have a leaf spring portion, as sla, Fig. 4, with which the auxiliary spring is combined. It is to be understood that-the invention is not limited to the use of two auxiliary springs in connection with one main vehicle spring, as is shown in F 1, but that one auxiliary spring only may be used with each main spring, the auxiliary springs being connected to the main springs preferably at rear ends as shown in Fig. 4.
